LipoDerm-Y is the most significant breakthrough in fat loss products to date. Containing the alpha 2 receptor antagonist Yohimbine Hydrochloride in
Avant Labs’ Patent Pending hydroalcoholic gel,
Lipoderm-Y releases large amounts of fat from the site(s) of application—far higher than is possible with alternate administration methods—while avoiding the negative side effects associated with systematic distribution. Coupled with a caloric deficit,
Lipoderm-Y ‘s targeted delivery accelerates localized fat loss in those typically stubborn areas, such as a woman’s lower body or a man’s midsection.
Lipoderm-Y makes what was once the myth of “spot reduction” a scientifically-proven reality.
Each 4oz bottle contains 18-30 applications, with 3 grams of Yohimbine HCl per bottle.
Topical Fat Loss Solution
I have previously stated that I believe transdermal prohormones to be
the most effective supplements ever to hit the market. That statement must
now be amended. Transdermal prohormones are indeed the most effective MUSCLE
BUILDING supplements ever to hit the market. But, topical fat loss products
have the potential to be an even bigger overall breakthrough in the never
ending quest to improve body composition.
There are four areas that need to be addressed in regards to topical fat
loss products and so called "spot reducers" in general. First, one needs
to distinguish between the products that are merely diuretics and those that
the manufacturer (assuming they have a brain) actually thinks might significantly
reduce body fat. Second, we have to have an understanding of the andrenergic
system, which is primarily what these products attempt to manipulate in order
to aid lipolysis Thirdly, we must have an understanding of transdermal/percutaneous
delivery, in order to understand why a topical formulation could present
advantages vs. orals, as well as to understand why every product of this kind
currently on the market, other than
LipoDerm-Y, fails. Within this category
there are 2 issues -- getting adequate amounts past the skin barrier and localizing
its distribution to adipose tissue. And, finally, there is the issue of Yohimbine
HCl vs.
yohimbe. After reading this, you should have an understanding of
why true "spot reduction" is physiologically quite possible, as well as enough
information to make an informed decision as to which products can and cannot
accomplish it.
Fat Loss Agents vs. Diuretics
Assuming we are not preparing for a photoshoot or competition, a product
that merely acts as a diuretic rather than significantly aiding actual lipolysis
is basically worthless. "Cutting Gel" belongs in this category -- its active
ingredient is aminophylline:
Aminophylline is a xanthine derivative, similar to caffeine, which is
not a particularly potent fat burner. In rat studies, it has shown good
thermogenic properties due to blockade of adenosine receptors (which provide
one of the negative feedback mechanisms for catecholamine induced thermogenesis)
and inhibition of phosphodiesterase (which degrade cyclic AMP) -- but this
is at extremely high doses, which would kill a human, so it is not applicable
(1,2). At therapuetic doses, only adenosine blockade occurs, which will act
to increase norepinephrine levels (3)-- but as you will see norepinephrine
stimulates alpha 2 receptors (bad) in addition to beta 2 receptors (good)
-- and in stubborn fat, alpha 2's outnumber beta 2's (4).
Like caffeine, it is a good diuretic (5), which would account for the
girth loss in the study they reference, which did not measure actual fat
loss (6,7). One study did look at fat depth after use of an aminophylline
cream, and no difference was found vs. control (8). As a local diuretic,
it might be effective, but as a true fat loss agent, it quite likely is not.
Precontest, such a product could be extremely beneficial if it would truly
localize the water loss, as it would allow one to get rid of extracellular
water with out the total body dehydration produced by drugs such as Lasix
-- thus, one could have fuller muscles, less cramping, etc. I am not particularly
familiar with the physiology of diuresis, as I have not researched it to
any great extent, so I don't know if it could actually be localized.
Products such as
LipoDerm-Y, Impact's DermaLean, and S.A.N.'s LipoBurn
(basically any of the products with yohimbine and a handful of other ingredients)
fall into the latter category. They are intended to manipulate the adrenergic
system, thus, theoretically, such products could cause true localized fat
loss if formulated properly:
The Adrenergic System
Introduction
One of the major contributors to body weight homeostasis in the human
body is the adrenergic system. There are two types of adrenergic receptors,
alpha and beta, as well as subtypes of each -- and depending on which are
activated, lipolysis (breakdown of fat) can be either stimulated or inhibited.
The most well-known adrenoreceptors to bodybuilders are the beta receptors.
These can be divided into subtypes 1, 2, and 3 -- and it is through these
receptors that drugs such as the ephedrine/caffeine stack and Clenbuterol
exert their effects. While Clenbuterol acts directly on beta 2 receptors,
ephedrine exerts its effects indirectly by stimulating the release of norepinephrine
(NE), the body's primary endogenous thermogenic hormone. Unlike Clenbuterol,
NE is not selective in its binding. In addition to binding to the beta 2
receptor, it also binds to both alpha receptors, as well as the beta 1 and
3 receptors. It is in regards to its binding to the alpha 2 receptor that
yohimbine comes into play.
Norepinephrine and Yohimbine
Activation of the alpha 2 receptor inhibits the release of NE. Thus, by
binding to this receptor, NE functions as its own negative feedback signal.
In other words, it shuts off its own release. Obviously, this is not a good
thing for fat loss. This is particularly true at rest (which, unless you
are a marathon runner is 95% of your day) -- this is because alpha 2 receptors
are activated at lower catecholamine levels than are the beta receptors (9).
Thus, thermogenesis is basically always turned off. It is the differences
in regional distribution of alpha 2 and the beta receptors that is responsible
for the gender differences in bodyfat storage (4). Basically, females have
a large number of alpha 2 receptors and few beta receptors in the gluteofemoral
area (hips, thighs, and butt), while men have the same problem in the midsection.
With exercise or the use of compounds such as the ephedrine/caffeine stack,
catecholamine levels can be increased to a point where the alpha 2 induced
inhibition of lipolysis is partially overcome (9). However, even then, the
alpha 2 receptors ARE still acting to reduce lipolysis.
Yohimbine is a selective alpha 2 antagonist (10) and can thus short circuit
this feedback loop, maximizing NE levels, thus maximizing fat loss, particularly
in these problem areas -- and even more so if we can achieve high levels
of yohimbine and NE in the adipose tissue. Unfortunately, to do so with orals,
or any other method that results in high blood levels means that we will
also have high levels in the heart and CNS -- thus, we will also have unpleasant
and dangerous side effects. Considering the subject of this article, I obviously
believe the solution lies in transdermal administration, but more on that
in a bit.
Blood Flow
A second, more indirect, mechanism by which Yohimbine can aid lipolysis
via the adrenergic system is by increasing peripheral blood flow (11, 12).
Adipose tissue is known to have rather poor vascularity. When triglycerides
are broken down into free fatty acids and glycerol during lipolysis, they
must also be transported away from the fat cell or they risk being reincorporated
into adipose tissue. Beta receptor activation causes vasodilation, thus
increasing blood flow, however, it does not increase enough to remove all
of the free fatty acids released during lipolysis (13). Alpha 1 and 2 receptor
activation, on the other hand, causes a decrease in blood flow (4, 14).
Thus, antagonism of the alpha 2 receptor with yohimbine would be expected
to increase blood flow, and thus increase the mobilization and disposal
of these FFA's, further aiding fat loss. And, again, the more we can get
in the adipose tissue without it reaching the heart and CNS, the better.
Percutaneous Delivery
Though the terms are often used interchangeably in the literature, there
are two distinct forms of drug delivery through the skin. The first, and
most common, is "Transdermal Delivery" -- this involves a drug bypassing the
skin barrier in order to be taken up into the bloodstream and distributed
systemically (15). This basically does the same thing as oral delivery, but
it is inherently time released and avoids first pass metabolism in the liver
which can limit bioavailability and cause hepatotoxicity, so it is is advantageous
for delivering many drugs.
The second is "Percutaneous Delivery" (15)-- with this method, one bypasses
the skin barrier, but with the purpose of delivering the drug to specific
target tissues in the body, while AVOIDING uptake into the blood and subsequent
systemic delivery. In the pharmaceutical realm, this has been pursued primarily
for antibiotics and NSAIDS -- the former, to avoid destruction of systemic
microflora (so-called "good bacteria"), and the latter to avoid hepatic recirculation,
which is responsible for gastrointestinal problems.
Unfortunately, the people who have developed most of the topical fat loss
products thus far either do not know about or understand this difference
or they do not understand its paramount importance in regards to adrenergic
modulators such as yohimbine. With prohormones, systemic uptake and distribution
is our goal -- they have poor oral bioavailability, so we are just trying
to avoid the liver in order to get significant amounts in the bloodstream.
However, with yohimbine and other adrenergic agents, oral bioavailabilty
is not the issue -- at about 22%, it is more than adequate (16). We can readily
achieve adequate blood levels with oral usage. The issue with these is that
as we increase dosages (and thus blood levels) in order to increase distribution
to adipose tissue to aid fat burning, we also increase distribution to the
heart and CNS where we create numerous unwanted side effects such as rapid
heart rate, high blood pressure, and overstimulation, which is particularly
noticeable with exercises. Yohimbine is also used clinically to produce
anxiety (17). Ideally, we want our drug to reach fat cells in high doses,
without the dangerous side effects of high levels in the heart and central
nervous system.
So, how do we do this?? Unfortunately, it is easier said the done. Typically,
drugs that penetrate the skin barrier and traverse the epidermis and dermis
are rapidly taken up by the dermal microvasculature, where they are delivered
systemically (just like with orals) -- this is well characterized in the
literature (15,18,19) -- with direct tissue penetration being limited to 1-4
mm, which obviously is not exactly deep into the adipose tissue. And, considering
that these substances have good oral bioavailability, if the dermal microvasculature
is not taken into account, we end up with a product that not only does not
localize delivery, it does not even deliver it systemically as efficiently
as an oral would do. Considering these products cost far more than there
oral counterparts, and could also be thought of as inconvenient in that you
have to rub them on your body, any supplement developer who doesn't take
dermal uptake into account has obviously missed the boat quite badly. And,
guess what... Not one single product other than
LipoDerm-Y does. And guess
what else -- they probably are not going to because we have filed a use patent
on the one carrier that has been shown in the literature to effectively accomplish
this.
Targeted Delivery
Let's now take a look at the literature that supports the idea of tissue
specific delivery of therapeutic substances. As mentioned previously, when
it comes to targeted delivery, the pharmaceutical realm, and thus the literature,
has primarily concerned itself with antibiotics/anti-fungals and NSAIDS.
We will look at the three most important ones.
Editors note:
I am not going to give the name of the substance that
has been shown to be effective as a vehicle for local delivery at this time.
I may do so when the product comes out, as it has to listed on the label.
Though we have filed a patent on it, there are many companies whom that will
not stop from attempting to steal our intellectual property. They lack the
intelligence and creativity to discover this sort of thing on there own (as
well as the integrity to think such things matter) so they choose to make
their money in this manner.
The first study (19b) involved the NSAID indomethacin as the drug to be
delivered. The drug was given orally (O) , topically without the "special
delivery solvent" (WO), and with the "special delivery solvent" (W). The
topicals were applied to the shoulder. For the first two hours after administration,
concentrations of the drug in the deltoid (which is obviously even deeper
than adipose tissue) were 5 times higher in W than in either O or WO. After
4 hours, it was 3 times as high, and by 8 hours it was still twice as high.
Obviously, the formulation containing the "special delivery solvent" was
vastly superior at delivering the drug to the target tissue. But what about
delivery to unwanted tissues? If it was just a case of the "special delivery
solvent" allowing more drug to cross the skin, this would not be a big deal
-- we could just use more. What we also need is for a minimal amount of the
drug to be delivered systemically, and once again, the "special delivery
solvent" was shown to be superior. Maximal blood levels of all three compounds
occurred at the 2 hour mark. W displayed levels about 1/3 that of O and 1/2
that of WO.
If the significance of this is not clear, it basically means that localized
delivery (what we want) per unit systemic delivery (what we don't want) for
W was 15 times that of O and 10 times that of WO -- and this was to the
muscle. Considering the adipose tissue is closer to the skin (which had
levels 10 times as high as the muscle) and that the joint capsule (which
is below the muscle) had levels 1/3 that of the muscle while with WO there
were equal levels at the muscle and joint, the ratio of delivery to adipose
tissue vs. systemic delivery for W is likely significantly higher.
The second study (19c) utilized the antibiotic erythromycin as the delivery
drug. Formulations for W and WO were identical to the above study. Oral administration
was not tested. Exact counts of the concentration in muscle tissue was not
reported, but the authors stated that after 4 hours, there was a major increase
in the muscle mass below the site of application (I have contacted the authors
to try to get exact data). Kidney and liver levels (indicative of systemic
distribution) were significantly lower for W than WO -- about 1/2 for the
former and 1/4 for the latter over 24 hours.
The third study (19d) we will look at utilized the antifungal griseofulvin
as the delivery drug and compared W with oral intake. The formulation for
W was the same as the previous two studies. The accumulation of the active
compound in the area of application for W was several hundredfold greater
than that which accumulated in the organs, and brain levels were non-detectable,
which is extremely important considering we are trying to avoid excessive
CNS stimulation -- and all of this was a full four days after application.
Compare this to oral delivery which showed concentrations that were approximately
identical in all areas, which would be expected if systemic uptake occurred.
Penetration Enhancement
I think it should be clear from the previous studies that it is quite
possible to achieve targeted delivery. However, if we cannot get adequate
amounts of our substance past the skin barrier, it is a mute point. And,
considering one of the skin primary purposes is as a water barrier (20),
hydrophilic substances such as yohimbine do not readily pass through (21,
22,23). Thus, we need to turn to the topic of penetration enhancement (for
a more thorough presentation, see my previous article Transdermal Delivery.
Yohimbine HCl, with a LogP of about .75 (24), is fairly polar/hydrophilic,
thus penetration enhancers should be chosen accordingly -- namely we want
those which affect the polar route. This rules out many commonly employed
penetration enhancers -- a fact many companies do not seem to be aware of.
Since there is very little direct data on penetration enhancement with Yohimbine
HCl, we will look at data when substances with similar physical properties
were used.
One promising chemical in this area is the terpene, l-menthol. Polar molecules
undergo significant hydrogen bonding in the stratum corneum, which is the
primary reason for their poor passage through the skin barrier (23). Because
of the presence of a hydroxyl (OH) group, l-menthol should bond to these
hydrogens (25), leaving our drug free to more easily traverse the skin barrier.
And, indeed the data has supported this. It increased the permeability coefficient
of mannitol 100 fold vs. control (26). In a study using Propranolol HCl which
has a partition coefficient almost identical to yohimbine (Log P .74 vs.
.75), it increased flux 1000 fold vs. control and also displayed the shortest
lag time of all terpenes tested (25). This is in contrast to d-limonene, almost
identical, structurally, to l-menthol, with the exception of lacking the
afore mentioned hydroxyl group, which has been shown to much less effective
for polar compounds (25, 27).
A second chemical is laurocapram. It too has been shown to be quite successful
with polar drugs (23,28,29) likely due to its increasing the water content
of the lipid phase of the stratum corneum. In one study, it enhanced the
flux of mannitol in a propylene glycol vehicle by over 350 fold (23). Unfortunately,
it displays a significant lag time -- meaning it can take as much as 10 hours
before it starts to work (30, 31, 32). Consider most of us shower daily,
this is not acceptable.
That brings us to n-methyl-2-pyrrolidinone (NMP). In combination with
laurocapram, in a study using morphine hydrochloride, which has physical
properties similar to Yohimbine Hydrochloride -- both polar molecules, molecular
weight of 322 vs. 390 -- and is thus quite applicable, NMP was shown to
significantly reduce the lag time (down to as low as 2 hours) as well as
increase the rate of penetration for the drug as indicated by blood levels
that were several thousandfold high than controls (32). In addition, it has
been shown in several other studies to enhance penetration of polar molecules
on its own, including a 256 fold increase with mannitol (23).
Finally, we have also added glycerol, which provides dual functions. First,
it helps to counter any skin irritation that might be caused by the alcohol
carriers. This is due to its increasing the water content of the skin, and
as alluded to in regards to laurocapram, this increase in water content has
the added bonus of increasing penetration for polar molecules such as yohimbine
(33, 34).
Yohimbine vs. yohimbe
Quite a bit of confusion seems to exist about the difference between Yohimbine
and
yohimbe. Yohimbine is the principal alkaloid from the herb P.
yohimbe.
However, there are 31 other yohimbane alkaloids that can be present in herbal
yohimbe preparations. Some of these have different and unknown selectivities
and potencies (and thus, effects) at the adrenergic receptors (35, 36) --
in addition, these preparations vary greatly from brand to brand and even
from batch to batch, as no standardization for extraction exists. In fact,
a recent investigation found that most over the counter preparations have
little to no actual yohimbine (37). And, even in the more potent preparations,
most people find a higher degree of undesirable effects with the herb vs.
pure Yohimbine (due to the afore mentioned 31 other yohimbane alkaloids that
can be present). With
LipoDerm-Y, you are guaranteed 25mg of pure, pharmaceutical
grade Yohimbine HCl per milliliter, without the added side effects from
other alkaloids - thus, allowing safer, more reliable dosing.
Dosing
Because some people are unusually sensitive to yohimbine, I would recommend
that one start with a small dose -- 3-4 squirts (50 mg) and then increase
the dosage by 25-50mg each day until side effects become unacceptable. Dividing
it into two doses would be ideal, but probably not necessary. In our beta
testing, we have gone as high as 400mg/day without significant side effects.
I have personally done this along with an EC stack, and the only time side
effects were particularly noticeable was during workouts.
Another thing to be considered when using yohimbine is that insulin blunts
its lipolytic effects. Because yohimbine is not reaching the pancreas in
significant amounts as it would with oral administration, insulin levels will
not be as high for a given amount of carbohydrates, but they will still be
elevated. Thus, it should ideally be used on a low-carb/ketogenic diet, or
at the very least, one should do moderate aerobic activity for an extended
period first thing in the morning on an empty stomach.
Conclusion
I think it should now be exceedingly clear that all topical fat loss products
are not created equal -- and you should now be equipped to make an informed
decision on which one to use. To sum up:
- The formulation should contain active ingredients that
are significantly lipolytic rather than mere diuretics.
- The formulation should use yohimbine hydrochloride rather
than the yohimbe herb.
- The formulation must not only include penetration enhancers,
but they must be appropriate for polar a molecule.
- The formulation must avoid uptake by the dermal microvasculature
or it will merely be an expensive, inefficient version of a pill.
- The formulation that meets these criteria is LipoDerm-Y.

Q: Spot reducing is a sham. Don’t we all know that?
A: This is the typically espoused assumption, and is in most cases correct.
When one consumes less calories then one’s body burns, a caloric deficit
is created which your body must make up for. The human body typically combats
this deficit through an increase in lipolysis (fat burning). Due to many
genetic and hormonal variations, fat may not be lost in a proportional manner;
that is, one may lose more weight from one’s arms and legs than one will
from his or her abs and hips.
Even so, when any type of significant lipolysis occurs, the body is in a
manner “spot reducing.” Several areas on the body experience a decrease in
girth in response to caloric deficit. This “spot reduction” is an effect,
not a cause. The misconception regarding “spot reduction” largely originates
from the fact that most assume this to mean the elimination of fat from a
given area with the use of a magical crème which initiates lipolysis
WITHOUT caloric deficit, or the use of toning exercises erroneously believed
to reduce fat concentrations in a specific area. This is simply not possible.
There can be no spot reduction without caloric deficit. The problem in the
past has been that we have had very little control in determining the areas
from which the body will preferentially burn fat. As already established,
caloric deficit alone will result in lipolysis, though its effects will be
experienced to a greater degree in some areas (“spots”) as opposed to others.
Control of this process has in the past been largely beyond our reach.
With the exception of the topical Yohimbine HCl products that have preceded
Lipoderm-Y, these topical “
fat burners” failed to address the issue of systemic
uptake (overall distribution into the blood stream), and were nothing more
than diuretics. Unlike the false claims put forth by the manufacturers of
these diuretic agents,
Lipoderm-Y does not pretend to generate a controllable
spot reducing effect without a concurrent caloric deficit.
As opposed to internal events dictating the origin of the fat stores to be
released and burned for fuel, this process can now be largely controlled
externally with
Lipoderm-Y; it will release fat from the site of application
and allow a degree of control over the patterns in which fat loss will occur.
Instead of reducing your calories, and then internally waiting for your body
to release fat from those “trouble spots” which are reluctant to let go of
adipose tissue,
Lipoderm-Y releases the fat from the site(s) of application,
and when combined with a caloric deficit, results in the effective realization
of controllable “spot-reduction.”
Q: How should LipoDerm-Y be taken?
A:
- Lipoderm-Y should be taken two times per day with 12 hours separating
application times.
- Lipoderm-Y should be used at least 2 hours before any activities in
which one will sweat or expose the skin to significant amounts of water,
due to the risk of the product washing off before it firmly binds with the
skin.
- Apply to one large area at a time, or several small areas at a time.
The dieter can only utilize so many of the stored calories being released
via LipoDerm; if an excess is released, those calories will not be burned
but simply redeposited. *An example of a “large” area is the thighs/hips/buttocks
or the abs/lower-back/obliques (or any combination thereof).
Q: It is recommended that one should optimally use LipoDerm-Y with a caloric
deficit of 500-1000 calories. This is 500-1000 calories below one’s daily
total maintenance intake—activity levels included—and not one’s Resting Metabolic
Rate (RMR) correct? I.e., my maintenance level is around 2040 for my weight,
but after working out three days a week and cardio 2-3 days a week, it's
actually closer to 3040 a day.
A: Correct.
Q: Is LipoDerm-Y allowed in drug free competitions?
A: Is Yohimbine allowed? If so, then there should be no issue with the use
of
Lipoderm-Y.
Q: Should I cycle this, and how long should a bottle of LipoDerm-Y last?
A: The only reason to cycle, other than financial constraints, would be the
possibility of alpha 2 receptor upregulation. No one has reported fat returning
upon cessation of use, so this is probably not much of a concern. 5 squirts
2 times per day, and 10 squirts 2 times per day, will last 36 and 18 days
respectively.
Q: I have heard that Yohimbine HCL can cause water retention. If I use
Lipoderm-Y, how many days out from a contest should I discontinue use so
I don't hold water?
A: One week should suffice, though with use of a diuretic, this time could
be reduced. Preparation-H Gel, used after the cessation of
LipoDerm-Y usage,
can expedite the removal of water and allow for a more rapid evaluation of
Lipoderm-Y’s results.
Q: Can I increase my dosage of LipoDerm-Y, above the recommended amounts?
A: You can do this, but you must keep in mind that Yohimbine’s primary function
is the mobilization of fat; it does not cause a significant increase in total
amount of fat burned (compared to something like DNP). Thus, the more
LipoDerm-Y
one uses, the more one is required to reduce calories for said dose to be
truly effective.
Q: When is the best time to apply LipoDerm-Y given that I consume a post
workout shake (insulin spike etc)?
A: Due to
Lipoderm-Y’s delivery method, Yohimbine HCl is gradually released
into your system, so the timing of the application is irrelevant regardless
of your training and diet schedule. Simply apply twice daily with 12 hours
separating each application. .
Q: Is it possible to stack Lipoderm-Y with ECA or NYC? What is the best approach
in these regards?
A: If one is supplementing with
LipoDerm-Y, ECA would be a better option
than NYC since
Lipoderm-Y already delivers high amounts of Yohimbine HCl
in a site-specific manner. ECA will elicit a far greater increase in NE,
and combined with the Alpha-2 blocking of Yohimbine, one should obtain better
results than would be offered by the coupling of
Lipoderm-Y with NYC.
Q: I have heard that Yohimbine HCl can cause High Blood Pressure. Per
6 squirts, your product contains 100 mgs of Yohimbine. Isn’t this dangerous?
A: Oral and topical (percutaneous in this instance) delivery of Yohimbine
elicit significantly different effects. Orally, one is primarily going to
receive Yohimbine’s stimulatory effects, with the blocking of A2 receptors
in other tissues being secondary. With
LipoDerm-Y, unlike with oral administration,
one bypasses systemic distribution and primarily targets the adipose tissue,
chiefly blocking the A2 receptors in the area of application only. This delivery
method minimizes Yohimbine’s stimulatory effects, thus allowing for a far
greater amount to be used.
Q: As is often recommended with oral Yohimbine, must I use LipoDerm-Y
with a Ketogenic diet? If not, what type of diet would be ideal?
A: Oral Yohimbine blocks the pancreatic A-2 receptors, increasing the response
of Insulin in the presence of carbohydrates; this is one reason it is often
recommended that it be used in conjunction with a Ketogenic diet (or at the
very least be reserved for use before low-carbohydrate meals). This is not
the case with
LipoDerm-Y however, again due to its percutaneous delivery
method. A caloric deficit is all that is required for
Lipoderm-Y to work;
the dietary method by which this deficit is achieved is of secondary concern.
Q: Can I use any of your other topical gels in addition to LipoDerm-Y?
A: Yes, one can use any of our other topical gels and
LipoDerm-Y simultaneously.
The only requirement when using two such products is that they not be applied
to the same area.
Q: What other supplements can be added to impart a synergistic effect
with LipoDerm-Y?
A: Other than an ECA stack, Sodium Usniate/Usnic Acid can be put to use,
as the uncoupling activity of SU/UA will aid in mobilizing fat, further enhancing
Lipoderm-Y’s effects.
